Abstract EN
Objectives.
Rheumatoid arthritis (RA) is a systemic, inflammatory disease.
Serum amyloid A (SAA) is an acute-phase protein, involved in pathogenesis of atherosclerosis.
The aim of the study was to assess serum concentration of SAA in RA patients, with reference to other inflammatory parameters and markers of extra-articular involvement.
Methods.
The study population consisted of 140 RA patients, low/moderate disease activity (L/MDA) in 98 (70%) patients and high disease activity (HDA) in 42 (30%).
Comprehensive clinical and laboratory assessment was performed with evaluation of electrocardiogram and carotid intima-media thickness.
Results.
The mean SAA concentration [327.0 (263.4) mg/L] was increased highly above the normal value, even in patients with L/MDA.
Simultaneously, SAA was significantly higher in patients with HDA versus L/MDA.
The mean SAA concentration was significantly higher in patients treated with glucocorticoids, was inversely associated with QTc duration, and was markedly higher in patients with atherosclerotic plaques, emphasizing increased CV risk.
SAA was significantly higher in patients with increased cystatin-C level.
Conclusions.
In RA patients, high serum SAA concentration was strongly associated with activity of the disease and risk of CV and renal involvement.
Recurrent assessment of SAA may facilitate searching patients with persistent inflammation and risk of extra-articular complications.
